Abstract
Sugar beet cyst nematode (Heterodera schachtii Schmidt) is transferred to sugar factories along with the sugar beet root and its surrounding soil, so called depot soil. Because of high infestation and the possible transfer and distribution of this soil, disinfestations of the depot soil should be taken into considerations. In order to assess the possibility for disinfestations of the depot soils in Esfahan sugar factory, an experiment with four treatments including; solarization (using transparent polyethylene sheet of 30µ thickness), undecomposed farm manure, the combination of solarization and farm manure and control (no operations) were compared in three replications at four various depths (0-15, 15-30, 30-45 and 45-60 cm) for two continuous years. Before and after the experiment, the populations of eggs and second stage juveniles were measured. The results showed that the combination integrations of soil solarization and farm manure had the highest effect and significantly reduced the nematode population as compared with the other treatments, especially at the depth of 0-15 cm. The population reductions in the respective depths in the combination of solarization and farm manure were 99.85, 99.28, 98.5 and 96.18 percent and those in control were 18.41, 36.14, 52.97 and 49.06 respectively. The farm manure and solarization treatments were not significantly different, but they were different from the control.
